Newly single Nick Cannon has lifted the lid on his romantic past with the Kardashians.
The father-of-two, who recently split from wife Mariah Carey after six years of marriage, dated Kim Kardashian from 2006 to 2007.
And he has now said that he also enjoyed a romantic tryst with one of her sisters, although he would not divulge who.
As a guest on BBC Radio 1Xtra studios to chat with Charlie Sloth, he took a lie detector test and when he was asked about whether or not he slept with a Kardashian other than Kim, he replied: "Yes. The ones that are of age."
He would not elaborate any further, saying that he always "gets into trouble" when he brings up his famous ex.
Cannon recently split from his superstar singer wife and his decision to speak about his former flame during his marriage is said to have caused a rift with Mariah.
According to insiders, an interview given by Cannon to Big Boy's radio show earlier this year was the last straw. In it he revealed during the so-called 'Big Boy's game' the names of five stars that he had slept with.
